Certificate
All product registered by LR’s in accordance with CE/PED.
API 594 and API 6D certificate issued by American Petroleum
Institute.
Inherently fire safe design
All VERVO check valves are inherently fire safe due to the valve
design, material and construction. In case of fire, both resilient
seat and metal seat valves provide metal to metal sealing
performance.
Light weight and reduced size
Installation costs are greatly reduced by VERVO’s light weight and
minimal space requirements. The compact design minimizes the
distance between flanges and is easily installed between all
flanges.
Horizontal/Vertical installation
Unlike most traditional swing check valves, VERVO check valves are
ideal for both horizontal and vertical pipeline installation.
